LUBRICATOR.

SPECIFICATION forming part of Letters Patent'No. 509,98, dated December5, 1893.

Application filed May 7, 1892. Serial No.' 432,225. (No model.) Patentedin England May l2, 1890, No. '7.372.

To @ZZ whom it may concern.-

Be it known that I, SAMUEL IRvINc., a subject of the Queen of GreatBritain, residing at Ilkeston, in the county of Derby, England, haveinvented certain new and useful Improvements in Appliances forLubricating or Cleansing the Bearings of Machinery, (for which I haveobtained a patent in Great Britain, No. 7,372, dated May 12, 1890;) andI do hereby declare the following to be a full, clear, and exactdescription of' the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

The object of my invention is to provide an oiler and cleanser that willdeliver oil or other lubricant directly and with a considerable amountof force into bearings or parts of machines and may also be used for thepurpose of forcing alcleansing fluid such as paraflin into such bearingsor parts of machines.

Referring to the accompanying sheet of drawings and to the letters ofreference thereon I will proceed to describe my invention.

Figure 1. is a perspective View of my improved lubricating appliance theworking parts being principally unseen and inclosed within the outercase or reservoir. Fig. 2. is a vertical section through innersurrounded tubes and working parts of the apparatus. Fig. 3. is a viewof the internal tubes and working parts showing their relative positionswhen the plunger is at its lowest point and the lubricant free to enterthe inner tube. Fig. 4. shows the same with the plunger raised, theentrance of the lubricant to the inner tube closed and the applianceready for ejecting the lubricant on the head of the piston being forceddownward. Fig. 5. is a View of the innermost tube into which thelubricant is drawn previous to its being forcibly ejected through thenozzle tube.

In carrying out my invention I provide a suitable case, reservoir orchamber such as A Fig. 1. to contain the lubricant in bulk and fromwhich the successive charges may be drawn into the inner tubehereinafter described. The lower extremity of this case may be threadedor screwed to engage with a threaded or screwed nozzle or delivery tubeor point such 4as B and the upper portion of the case A may carry atapped or threaded socket or orifice in which engages a screwed bossattached to or surmounted by a flatthumb piece C and through which asthrough a stuffing box passes a spindle or piston D terminating in aremovable head or cap E and normally held up by a spiral spring such asF embracing said piston between the top of reservoir and cap E. Thisspindle or piston terminates in a plunger G hereinafter furtherdescribed. Attached to or forming a portion of the nozzle B is astationary tube I-I Figs. 2, 3 and 4, at the lower portion of which is asmall orifice I through which may iow the oil or lubricant contained inthe reservoir A and be forced thence through the small opening b of thenozzle or point B by the action of the plunger G and piston D. At theupper end of the tube is a vertical slot .I in whichapinKscrewedintothe-piston or plunger D may slide. This tube H is surrounded by asecondmovable tube L in which isa wider slot M with cani shaped ends andthrough this projects also the pin K which partially revolves the tube Lround the tube H on the rising and falling of the piston. Near thebottom of the outer tube L is a hole or orice N through which the oil orlubricant contained in the reservoir A may pass and thence through thehole I when the two orifices t' and N become coincident by reason of theforcing down of the piston and plunger. The working of the piston causesa pumping action, the oil or lubricant being first drawn through theholes in the tubes and then ejected through the nozzle B.

When not in use the piston or plunger is kept firmly down by a holdfastformed as follows: On the boss or thumb piece C is provided a fork Pthrough the head or cross head of which works a screw Q terminating in amilled head R. Vthen it is desired to secure the piston the head of thefork Pis brought over the cap E the piston being depressed and the screwQ is turned until the piston is firmly held home. Then the holdfast isreleased the piston rises, the fluid is drawn from the chamber orreservoir A through the holes I and N into the inner tube H and forcedout through the nozzle opening b on the return of the plunger the tubebeing recharged on the withdrawal of the pressure. Oil or other uid isintroduced into the reservoir through a capped orifice or other devicesuch as S.

Whatldo claimas my inventiomand desire to secure by Letters Patent, is
